the ______ ________ is the overall force acting on an object after all the forces have been added or subtracted

Do you have choices available? I have always used "resultant" but other words can describe that also.

The blank space in the statement is filled by the term "net force". The net force is the overall force acting on an object after all the forces have been added or subtracted. It determines the acceleration or motion of an object according to Newton's second law of motion. To calculate the net force, you need to follow these steps:

1. Identify all the individual forces acting on the object.
2. Determine the magnitude and direction of each force.
3. Add all the forces acting in the same direction together. If the forces are acting in opposite directions, subtract the smaller force from the larger force.
4. The resulting force is the net force acting on the object.

Remember that forces are vector quantities, meaning they have both magnitude and direction. The net force should be expressed as a vector with both magnitude and direction.
